C＃探测并捕获Javascript Alert（）和Confirm（）
所以我已经做了一段时间的研究而且我已经走到了尽头。 我正在做一些IE自动化。 在C＃/ .NET中，如何探测和使用javascript alert（）或confirm（）以便我可以执行诸如获取文本并单击OK \ Cancel按钮之类的操作？
更新 ：
我需要重申一下：我需要能够从alert（）或confirm（）中提取并validation文本，并向其发送OK或Cancel click。 这种测试的一个例子是确保当我点击删除时，confirm（）没有说“你确定你想去墨西哥吗？” 或除了正确信息之外的任何其他内容
为了以防万一，请允许我重申：出于本次测试的目的，我无法控制相关网站的来源。
最后，我正在使用SHDocVw.InternetExplorer 。
FindWindow – 会让你亲近; 你确实想要一个窗口句柄，但你肯定不知道如何找到它。
更好的方法是使用EnumWindows.Here是一个例程，您可以每隔一两步运行一次，它将为您提供有关系统上每个窗口的大量信息，然后您可以对其进行分析。 您可以检查窗口类型，其中的文本，获取按钮，并向右侧发送单击消息。 它会让你做你希望能做的一切。
要获取文本，您发送一个wm_gettext，对于按钮，您可以使用wm_click。
抱歉C.我能找到的下一个最佳例子是LISP。 花点时间阅读代码，你会看到这个想法是什么。 匹配function有助于确定文本是否正确而不完全了解它。
如果你能在c＃中设法做到这一点我打赌你会得到更短的解决方案。 （你可以在EnumWindows的输出上使用LINQ吗？;-)

我认为你将不得不使用FindWindow，SendMessage等。这就是WatiN如何处理对话框。
我认为您正在寻找的是IDocHostshowUI COM接口。 如果我正确阅读文档并且我的假设是正确的，则在JavaScript中调用alert（）或confirm（）时将调用ShowMessage函数。
我自己没有这样做，所以我只是在猜测。 以下是某些人在C＃中显示使用该界面（以及许多其他界面）的示例。 WebBrowserSample2听起来像你在寻找。
